Reformer basics

Springs, straps and grip socks: the reformer explained

Colour-coded springs on an Align-Pilates reformer at La La Pilates Glasgow

A reformer is a padded, sliding platform (the carriage) mounted on a frame, connected to colour-coded springs that add resistance or support. You push and pull the carriage using a footbar and a pair of straps. Every part adjusts, which is why one machine suits complete beginners and experienced clients alike. Here's what each bit does.

The carriage

The moving bed you lie, sit or kneel on. It glides along the frame as you press or pull, and controlling that glide — smoothly out, smoothly back — is where most of the work happens. The shoulder rests at the top keep you in place when pushing.

The springs

Underneath the carriage sit the springs — on our Align-Pilates reformers they're colour-coded by strength. Springs do two jobs at once: they're the resistance you work against, and the support that steadies you. That's the cleverness of the machine — adding a spring can make one exercise harder and another one easier. Choosing your springs is my job, not yours, and it's how the same class works for every level.

The footbar

The padded bar at the end of the machine. Press your feet (or hands) into it to move the carriage — the very first thing you'll do in a beginner class is footwork here, learning how the springs feel with your spine fully supported.

The straps

Two long straps with soft loops for your hands or feet. They connect through pulleys to the carriage, so arm circles, leg work and some of the more flowing exercises all run through them. They look intimidating; they're actually one of the gentlest parts of the repertoire.

The box

A firm padded box that sits on the carriage to create new positions — seated, lying over it, or side-lying. If your class uses it, I'll set it up for you.

Grip socks

Socks with rubberised soles. They keep your feet from slipping on the footbar and carriage and keep things hygienic in a shared studio. They must be worn for all sessions — bring a pair with grips on the sole.

Do heavier springs always mean harder?

No — heavier springs add resistance to pushing movements but give more support in others. Sometimes the lighter spring is the harder option, because your core has to control the carriage. That's why we set them for you.

Do I need my own grip socks?

Yes — grip socks must be worn for all sessions. Any socks with grips on the sole work.
